Be it `iinoivn that l CLARENCE S,.'lnns'roivV .r ,fc m 3 citizen oi tne United btates, residing at man4 Diego, in the county of San Diego and State oiltaliiornia, have inventedcertainnew and useiiul improvements in Resilient Channel,

and Cushion Tires, ot' Whiclithe .following is a specification.

lhis invention relates to vvehicle tires ot' the solid type provided With channels or voids and cushions, adapted in particular -for vehicles which carry heavy loads Such as trucks,y and also slow moving Vpleasure Vefhicles particularly of the electric driven type.

The principal object of my invention is to; providein a tire ofthe solid` typ'ejlas dis. tinguished from a pneumatic tire) an annu-V lar core or central portionxof resilient niaterial havinfffan outer and .inner series ot straight voids, approaching av crescent shape in cross section, extending transversely V'through the tire, in such a manner vthat those voids placed nearer to the outeryperiphery. of the'core Willbel spacedbettneen the voids placed nearerto the inner periphery of the core; also so arranged that the tvvo series of voids will overlap eachother so that thereV will always be an` airspace onfanyradial' line drawn fromthe vWheel center to the outer periphery of the tire into which solid matter orn the core will be forced, When under Ypressure, thereby increasing the resiliency of the tire as Well as preventing-road or load shock hicle body. s Another object is to inclose this core onl its inner and outer periphery, yvith iiat rubber rings, Hat metal rings and Wooden felv loes,V for the purpose of increasingr thev strength and'durability ofthe tire, a metal rim7 to .'Which is fitted asolid rubber treadv forming the outer periphery-of the completed tire, being mounted on the outer pe- '1 riphery of the outer Wooden itelloe :n ive-llv known mannen'all in order to Withstanffl load and road shock and add to the resilieiicy` of thetire. Q j A Anotherobject is to provide for the eK- clusionao dust Vand dirt or mud from the voids by placing" an annular iiat 'rubber' flange lon each side of the tiretobe held .in`V

place by grooves in the outer and'innermetal rings which 'inclose the outer andinner periphery of the core.

ribs G and F beingV supportedby the elastic'V Webs H and H. The voids I and K are pref- V erablyformed in'moulding the' core E5 Figi l, and are a near crescent shape in cross sec-1 tion.` The concayesides of the voids Ii'ace theouter periphery ot the tire While the-cone.

caire 'sides or" the voids 'K ia-ccthe innerl e-i riphery :of theftire. areplaced in staggered position to each other,l Y

, `V The principalY portion ofthe ltire is the but at the same time they overlap each other so. that whatever position the wheel rests on the tread there is always an air chamber or void on any radial line which might be drawn from the center of the wheel to the outer periphery of the tire, which provides at all times tor interior displacement ot the solid material when under load pressure.

The ribs Gr are formed between the inner series of voids I and their bases are adjacent to the inner periphery of the core E.' The posts F are formed between the outer series otl voids K and their bases are adjacent to the outer periphery of the core E.

Covering the outer periphery of the core E and preferably vulcanized to the bases oi the posts F is a flat annular piece of rubber or rubber compound L to prevent Vcircumferential movement of the posts F when under stress or strain as shown in F ig. l. Likewise covering the inner periphery of the core E and preferably vulcanized to the base of the ribs G isv another fiat annular piece ot rubber er rubber compound D to prevent circumferential movement of the ribs G, Fig. l. It is not intended that there should be any circumferential movement of either of the posts F or the ribs G when under load pressure. The resiliency of the tire is obtained by the interior displacement of the posts F and G and elastic webs H and H into the voids I and K, Fig. l. The core E is neXt inclosed on its inner and outer periphery by thin metal bands, the metal band C being adjacent to the inner periphery and the metal band M being adjacent to and surrounding the outer periphery ot the core E. Thefcore E is preferably vulcanized to the nietal bands C and M, to make a compact strong and durable inner portion Jfor the tire with corresponding resiliency. The metal bands Cv and M are provided respectively with grooves C and M, in which are fixed tlat, thin, annular rubber sheets It kwhich lie flat against the 'sides of the core E for the purpose of covering and excluding from the voids I land la, dust, dirt, mud and water, which would, it not excluded, clog up the voids and lessen the resiliency of the tire.

A wooden felloe N is preferably mounted on the metal band M, and the metal rim Ii, having turned up edges P, to which. is preterably vulcanized an outer portion ot the tire-the thread portion-ot rubber or rubber compound. is mounted on the said woodenfelloe N.

Screws S `are preferably passed through the rim P, wooden felloe Ninetal band M, rubber band L and partially into the bases of the posts F, and also are preferably passed through the metal band C, rubber band I) and partially into the base of the ribs G, to make the tire compact and prevent ycircumferential movement of the various parts to which reference is made and as shown in Figs. l and 2 of the drawings.V

The tire, as shown in Fig. 2, modied drawing, differs from the tire shown in F ig. l, in that the Wooden telloe N is omitted and the metal rim P is mounted on the metal band M. .The metal bands M and C are not provided with slots or grooves as the rubber sheets R are yomitted and. in their place I provide an annular rubber casing' R whichV entirely surrounds the'core E. The casing R is preferably vulcanized to the outer and innerperiphery otthe core I@ but not to the Y interfere with the resiliencysides as it would of same.

VI claim:
